要实现将PDF中表格内容生成Excel文档,需要使用一些Java库来实现。以下是可能的实现步骤:
1. 使用Apache PDFBox库来读取PDF文件并提取表格内容。PDFBox是一个开源Java库,可用于读取和操作PDF文件。您可以使用以下代码来提取表格内容:
```
PDDocument document = PDDocument.load(new File("example.pdf"));
PDFTextStripperByArea stripper = new PDFTextStripperByArea();
stripper.setSortByPosition(true);
PDFTextStripper tStripper = new PDFTextStripper();
String pdfFileInText = tStripper.getText(document);
String[] lines = pdfFileInText.split("\\r?\\n");
for (String line : lines) {
// process table content
}
document.close();
```
2. 解析表格内容并将其存储在Java对象中。这可以通过使用正则表达式来解析每行表格内容来实现。您可以使用以下代码来解析表格内容:
```
Pattern pattern = Pattern.compile("([^,]*),\\s*([^,]*),\\s*([^,]*)");
List<TableData> tableDataList = new ArrayList<>();
for (String line : lines) {
Matcher matcher = pattern.matcher(line);
if (matcher.find()) {
TableData tableData = new TableData();
tableData.setColumn1(matcher.group(1));
tableData.setColumn2(matcher.group(2));
tableData.setColumn3(matcher.group(3));
tableDataList.add(tableData);
}
}
```
3. 使用Apache POI库将表格内容写入Excel文档。POI是一个Java库,可用于创建、读取和操作Microsoft Office格式的文件。您可以使用以下代码将表格内容写入Excel文档:
```
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Table Data");
int rownum = 0;
for (TableData tableData : tableDataList) {
Row row = sheet.createRow(rownum++);
row.createCell(0).setCellValue(tableData.getColumn1());
row.createCell(1).setCellValue(tableData.getColumn2());
row.createCell(2).setCellValue(tableData.getColumn3());
}
FileOutputStream out = new FileOutputStream(new File("table_data.xlsx"));
workbook.write(out);
out.close();
workbook.close();
```
最后,您需要将上述代码组合在一起,并处理任何可能的异常。
